AVENTIS ENERGY ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT FOR STING COPPER PROJECT IN NEWFOUNDLAND & LABRADOR

Aventis Energy Inc. has filed a technical report dated Dec. 24, 2025, with an effective date of Dec. 9, 2025, entitled "Technical Report on the Sting Copper Property, Newfoundland And Labrador, Canada," prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, on the company's Sting copper project. The report was written by independent qualified person Alexander Timofeev, PhD, PGeo, of Dahrouge Geological Consulting Ltd. The report is available on SEDAR+ and is published on Aventis's website.

Key technical report recommendations

Further work on the project is recommended to advance priority target areas within the Jumbo-Red Lode and Crabb Brook claim blocks, where recent exploration has identified anomalous geochemical and geophysical signatures prospective for VMS-style (volcanogenic massive sulphide) copper-zinc mineralization. At Crabb Brook, key targets, including Buck Head Brook, the headwaters area and an eastern chargeability anomaly identified from VTEM (versatile time-domain electromagnetic) data, warrant follow-up. A phase 1 program of soil sampling and prospecting is recommended to refine these targets, followed by a ground-based IP (induced polarization) survey to better define chargeability responses and prioritize future drill testing.

Qualified person statement

The scientific and technical information contained in this news release has been reviewed, verified and approved by Alexander Timofeev, PhD, PGeo, of Dahrouge Geological Consulting, a qualified person (QP) as defined under National Instrument 43-101.

The information presented herein is derived from the report. The report summarizes geology, mineralization, historical exploration and recent work completed on the project by the company.

Samples referenced in the report were collected through industry-standard exploration methods, including prospecting, soil sampling, channel sampling and diamond drilling programs completed in 2024 to 2025. These samples were prepared, processed and analyzed at accredited laboratories using appropriate analytical techniques, including ICP-based (inductively coupled plasma) multielement methods.

Quality assurance and quality control (QA/QC) procedures included the insertion of certified reference materials, blanks and duplicate samples at regular intervals throughout the sampling process, in addition to internal laboratory QA/QC protocols. Based on these procedures, the analytical results are considered reliable for the purposes of this disclosure.

Certain information disclosed herein relating to historical exploration activities conducted by previous operators is historical in nature. A qualified person has not verified these data and therefore the data should not be relied upon. However, the company considers such information relevant as an exploration guide in assessing the mineralization potential of the project.

The project is an early-stage exploration project, and there are currently no mineral resource or reserve estimates defined on the project in accordance with NI 43-101 standards.

About the Sting copper project

The Sting copper project comprises five mineral licences covering approximately 3,675 hectares located in western Newfoundland and Labrador, Canada, and is 100 per cent owned by the company. The project is situated within the Bay of Islands ophiolite complex and is prospective for VMS-style copper-zinc mineralization. The project has seen multiple phases of historical exploration, including prospecting, geophysics and drilling, and more recently has been advanced through soil sampling, channel sampling, geophysical surveys and diamond drilling programs completed in 2024 and 2025.

About Aventis Energy Inc.

Aventis Energy is a mineral exploration company dedicated to the development of strategic projects comprised of battery, base and precious metals in stable jurisdictions. The company is working to advance its Corvo uranium and Sting copper projects. The Corvo uranium property has historical drill holes intersected multiple intervals of uranium mineralization, notably along a strike length of 800 metres between historical drill holes TL-79-3 (0.116 per cent U3O8 over 1.05 m) and TL-79-5 (0.065 per cent U3O8 over 0.15 m) (high-grade uranium at surface with the Manhattan showing (1.19 to 5.98 per cent U3O8) and SMDI showing 2052 (0.137 per cent U3O8 and 2,300 parts per million (ppm) thorium (Th))).

The Sting copper project covers approximately 3,700 hectares and recently had results of 54.8 m at 0.32 per cent Cu starting at a depth of 27.0 m, with higher-grade intervals including six samples (more than 0.5 m length) ranging from 0.96 per cent to 5.43 per cent Cu. High grade samples include 0.5 m at 2.85 per cent Cu and 0.5 m at 1.92 per cent Cu with an additional broader interval of 31.1m at 0.27 per cent Cu.
